ADOLF HOLLMANN, 0F MONTCLAIR, NEW J ERSEYJ DOOR-ADJUSTING DEVICE.

oa: ,osa.

Application filed February 24, 1909. Serial No. 479,724.

To all whom it may concern:

Be it known thatI, Anonr T'TOLLMANN, a citizen of the United States, residing at Montelair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Door-Adjusting Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification. 1

This invention relates to an improved device for adjusting doors, and is designed to provide means for withdrawing the hinge of the door toward the door casing or permitting it to be drawn partly therefrom so "that the fit of the door against the doorframe, opposite to the hinge, can be ad justed. The device also provides means for adjusting the door vertically, and in this way a means is provided for making a door lit a doorway withoutplaning the same, and

particularly where the misfit has'oocurred through the settling of a structure and but slight adjustment is needed. The planing of doors, when they are to be fitted, takes off the varnish and spoils the appearance of the door, and it is to ,avoid this and also to avoid 'the necessity of a carpcnters service that this invention is devised.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a plan of the device. Fig. 2.

is a face view of a door 'asing with the molding strip removed. Fig. 3 is a section through the frame looking in the direction of the hinge, and Fig. 4 is a modification of the hinge. v

The device can he installed in a door casing of usual construction, but I prefer to make the frame out of the parallel strips 10, on the outer side having a board 11 to join them on that end, and on the inner end having a strip 12. To the strip '12 are secured brackets 13 which are right-angled in form and are secured by the screws 14 to the strip 12, these screws passingthrough the slots 15 in the brackets 13. The brackets are fastened to a door strip 16, being secured thereto by the screws 17. Passing through the door strip 16 and also through the bracket 13 is a bolt 18 which is provided with the countersunk head 19, which head is preferably passed through the perforation 20 in one of the hinged leaves of the hinge, as will be hereinafter described, this perforation being shown particularly in Fig. 4. The bolt 18 passes into the rear strip 10 and is provided with a nut 21, which nut is fastened in a groove 22st) that it is prevented from turning, and when the screws 14 are unloosened from the bracket so as to allow the brackets 13 to slide, if a screw-driver is used to operate the bolt 18 in one direction, the bolt will screw into the nut and draw the door strip in toward the rear of the casing and relieve any binding of the outer .end of the door with the door frame. If the fit is not tight enough, the screw can be turned backward to unscrew it from the nut 21, and the spring 23, which encircles the bolt and bears on one end on the bracket 13 and on the other end on the rear strip 10,

molding strip and enter the strip 12 so thatwhen the door strip 16 is adjusted by screxw ing tightly up on the screws 26, the molding strip binds tight against the door strip and assists in holding it in position and makes the parts compact and tight.

To secure a vertical adjustmentof the door, I provide a hinge which consists of two leaves 27 and 28, one of which is fas- V tened to the dooand the other to the door strip. ()ne'of the leaves, as 28, hasa post 28) which has a shoulder 30 thereon, beyond which the post has a reduced stenrE-Bl, which sjem fits'up into a socket 232 olrtlie other leaf, which socket is closed at the top.- 'lhrough the closed top of the'socket 32 is "tn-ranged a screw 33, lI1(l\Vl10ll;llll'S is v crewed the socket rises'up, because the end of tithe screw rests on the post 31' and thus the that 27 is raised, carrying the door with it. When the door is to be lowered, the rotation of,the screw 33 the other way will permit the socket- 32 to ride'down on the post 31, as will be understood.

The device is applicable to. any style of door or casing, although it'is preferred to use the form" shown herein that forms the.

chamber between the strip llan'd the molding stri 24, with the back strip 10 as means for hol ing the bolt 18, and in this chamber Specification of Letters Patent. Patentd Sept. 14, 11909.
